Title: Improvements in or relating to ammonium sulphate saturates
IPC: C01C1/242
Filed: 1952-09-22
Abstract: In the production of ammonium sulphate by absorbing ammonia in sulphuric acid contained in a saturator, slurry containing ammonium sulphate crystals is continuously removed from the saturator and reintroduced at a point immediately adjacent to that at which the crude gas enters the saturated solution.  By this means supersaturation is relieved by increasing the size of the crystals rather than by forming new crystals.  As shown, slurry is passed from the bottom of a saturator 11 via pipe 19, pump 21 and pipe 23 to an annular distributing duct 24 surrounding the cracker head 13.  The walls of saturator 11 are sprayed by water issuing from orifices 25b <PICT:0747657/III/1> in annular pipe 25.  The density of the slurry at the bottom of the saturator is controlled by passing in gas from a number of orifices in a turbulating coil 17.

Abstract: 285,522. Steuart, D. S. S. Aug 18, 1926. Addition to 281,801. Mouthpieces and attachments.-The speaking tube attachment of the parent Specification is modified in construction in regard to the ferrules, flexible tube, and to the construction and centring of the wires giving an adjustable rigidity to the devices. The flexible tube t is made of uniform bore or tapered from the mouthpiece to the end joining the telephone and is formed of coiled wire, preferably of tempered duralumin surrounded by rubber-proof material furnished with a covering of braided cotton or other material. One end of this tube is attached to a ferrule f<1> adapted to screw into the microphone box of a telephone &c. and the other end to a ferrule f adapted to screw into a mouthpiece. The ferrules are flanged and the ends slotted vertically to receive pins p passed through conical cap pieces h riveted to the ends of the rigidity imparting wires, such pins being secured by screwed washers r. In the example shown in Fig. 1, the rigidity imparting wires are formed of one or more lengths of single or stranded cable w made of annealed aluminium varnished and enamelled, which is inserted into a length of thin corrugated steel tubing packed between its corrugations with asbestos. The opposite ends of the steel tube may be twisted in opposite directions to reinforce the aluminium wire, the ends of the composite wire being riveted to conical-ended caps h. In another form, the ends of the wires are passed through slots in the ferrule and clamped in the grooved flange by the washer r. In this case the mouthpiece ends of the wires are inserted into slanting holes in the ferrule next the mouthpiece. Fig. 5 shows a construction wherein the cap h is gripped and centred by a split ferrule k, an arm of which passes through the slot and is bent round to lie in the groove, flange wherein it is secured bv the washer r. In a further modification, the cap is centred by a spring coil, the ends of which are passed through the slotted ferrule and secured in the groove of the flange by the washer r.

Title: Improvements in the polymerization of unsaturated organic compounds in aqueous suspension
IPC: C08F2/22
Filed: 1955-08-18
Abstract: Polymerization of an unsaturated organic compound which is water-insoluble and liquid under the polymerization conditions is carried out in aqueous suspension in the presence of a water-soluble copolymer of N-vinylpyrrolidone-2 and a minor amount of an ester of an acrylic acid, such as methyl, ethyl or butyl acrylate, as suspending agent.  The unsaturated organic compound may be methyl methacrylate, styrene or a substituted styrene, such as a nuclear-substituted mono- or di-methyl styrene, alphamethyl or meta-ethyl styrene or an alkoxy or chlorostyrene. The styrene or styrene derivative may be copolymerized with acrylonitrile, N-vinyl carbazole, vinylidene chloride or methyl methacrylate.  The polymerization may be carried out in the presence of a catalyst such as benzoyl or ditertiary butyl peroxide or azo isobutyronitrile. Porous masses may be obtained by adding to the monomers easily volatile non-polymerizable organic liquids such as butane or pentane or their mixtures with hexane, cyclohexane or with hexane and cyclohexane, to obtain polymer granules containing the liquids in dispersion, which are then heated to a temperature above the boiling-point of the organic liquid and above the softening range of the polymer. Examples describe the production of copolymers of N-vinylpyrrolidone-2 and methyl acrylate or methacrylate in aqueous solution in the presence of azo-bis-isobutyric acid nitrile or hydrogen peroxide as catalyst.

Title: Improvements in or relating to telephone systems
IPC: H04Q3/00
Filed: 1924-10-09
Abstract: 247,247. Western Electric Co., Ltd., (Western Electric Co., Inc.). Oct. 9, 1924. Order apparatus.-Figs. 8 and 9 show the apparatus at a manual exchange for displaying to an operator a wanted number which has been transmitted from an automatic exchange by means of code impulses. The impulsing circuit includes in series oppositely - polarized relays 800, 801 and a marginal relay 802. It will be assumed that the wanted number is 2531. Relay 801 responding to the first impulse. of the first digit 2 (comprising a strong negative impulse followed by a weak negative one) operates relay 804 in series with the left-hand winding of relay 803 which, however, does not energize. Relay 804 energizes relay 808. Marginal relay 802 also responds to the first impulse and extends the lead 828 (earthed by relay 821) over conductor 831 to operate relay 900 which locks up. At the end of the impulse, relay 803 energizes over both its windings in the locking circuit of relay 804. The second negative impulse of the digit operates relay 801 only. Relay 801 short-circuits relay 804 which releases, and at the end of the digit relay 803 also releases and removes a short-circuit from relay 807 which then energizes in the locking circuit of relay 808. Relays 807, 808 transfer the operating conductors from the first relay set 909 - - 908 to the second set. 915 - - 903. The second digit 5 (consisting of a weak negative followed by a strong negative impulse) similarly effects the operation of relay 903. For the third digit 3 (consisting of a weak positive, a strong negative and a weak negative impulse) the positive impulse operates relay 800 which in turn energizes relay 804; the strong negative operates relays 801, 802, 804, 905, and the weak negative releases relays 803, 804. The final digit 1 (a weak positive followed by two weak negative impulses) results in the operation of a relay 906. When relay 813 operates at the end of the last digit, the wanted number is displayed on lamps 910, 913, 917, 920. When the operator plugs in to the wanted line, the circuit of relay 821 is opened and the indicator apparatus released.

Abstract: 730,633. Memorandum appliances. LAMSON PARAGON SUPPLY CO., Ltd. March 20, 1952 [Oct. 3, 1950], No. 24190/50. Class 16. In apparatus for separating carbon paper or transfer strip or strips from interleaved relation with respect to superposed record webs, the carbon paper or transfer strip or strips is or are positively drawn off from the record webs by feeding it or them between a lower driven roller and an upper roller resting thereon, the driven roller being rotated by friction drive means which permit a degree of slip in the drive to the roller such that any drag which would prevent the free feeding of the transfer strip or strips will cause slip in the friction drive means rather than between the rollers and the transfer strip or strips. The superposed stationery web A after use in a tabulating, recording, writing or like machine, is fed over a curved plate 17 and through the apparatus by means of a tractor unit 3, in a housing member 2, having projecting pins to engage in marginal apertures, the unit 3 being driven by gearing from an electric motor 4. The web A is passed between cutter discs 26, 27 which cut off the marginal stub 28 joining the webs and carbon strips, as by adhesive, and which contain the feed apertures, and the stub 28 is delivered by a chute 29 into a compartment 30 in the main frame 1 of the apparatus. The separated record webs a<SP>1</SP>-a<SP>4</SP> are fed over guide plates 18-21 and into trays A<SP>1</SP>-A<SP>4</SP> in which they automatically refold into zig-zag form. The interposed carbon paper strips b<SP>1</SP>-b<SP>3</SP> pass over guide rollers 22-24 and 22a-24a and a common guide roller 31 to a driven roller 9 and upper roller 10 from whence they fall into a compartment 25. The rollers 9, 10 are removably mounted by means of axles 11, 15 in vertical bearing plates 12, the axle 15 being positioned in slots 16 so that the roller 10 rests freely on the roller 9. One end of the axle 11 has a pulley 13 having a V-groove for engagement by an endless belt 7 also of V-section which is supported in engagement therewith by a jockey pulley 14 to allow slip under tension. The belt 7 passes round wheels 6 and 8, the wheel 6 being driven from the motor 4 by a belt 5 and the belt 7 being driven thereby at a slightly greater linear speed than that of the carbon strips so that they are maintained taut, but slip takes place between the belt 7 and pulley 13 as soon as there is too much pull thereon. The guide rollers for the carbon strips are preferably highly polished to prevent offsetting of the carbon and are detachably mounted to facilitate threading of the strips.
